DRIVING APPARATUS FOR- BOATS.

' of driving apparatuses for boats (especially to so-called outboard-motors) the propeller shaft of which can be swung half a revolutionin a horizontal plane, so that the boat carrying the driving apparatus can be driven forward as well as backward without reversal of the working direction of the motor belonging to the driving apparatus. According to this invention the reversal of the direction of motion of the boatv takes place by means of the tiller belonging to the driving apparatus being turnable also in vertical direction and connected with the propeller shaft in such a way that when the tiller is turned, that is to say is raised or lowered, from a position, corresponding to motion forward, into another position, the propeller shaft swings half a revolution, in consequence whereof the boat Wlll be driven backward. Through a smaller turmng of the tiller, it being raised or lowered, the boat can also by means of thls arrangement be steered sideways. I

On the accompanying drawing is shown by way of example a form of thls'mvention, applied to an outboard motor.

Figure 1 shows the outboard motor seen' from one side, while Figs. 2 and 3 show horizontal sections of the same, taken along the lines AA and BB in Fig. 1.

The motor shaft and the extension of the same are-as is usualsurround ed by a sleeve 1 (the shaft sleeve) which is rotatable around said shaft and which sleeve at its lower end carries a casing 2, 1n .whlch the propeller shaft is journaled. The rudder 3 is attached to a sleeve or ring 4: which can be turned around the shaft, sleeve 1 and which ring by means of a bar 5, extending along the shaft sleeve, is connected with l another sleeve or ring 6 which is likewise rotatable around the shaft sleeve 1 to which the tiller 7 is fixed. When the tlller 7 is turned in the one or the other quarter in thev transverse direction of the boat,the

boat will, as will easily be understood,.be steered in accordance therewith. The tiller is fixed to the ring 6 by means of pivots 8, which extend from the ring in the trans verse direction of the boat (in the ordinary position of the parts) and around these pivots the tiller can be turned in a vertical direction. An extension of' the tiller 7', which. extension is directed backward, is provided with a conical toothed segment 9 WlllCll is in engagement with a conical toothed wheel 10, fixed to the shaft sleeve 1. When the tiller 7 is raised from the position, shown by full lines in Fig. l, which position corresponds to motion forward of the boat, into the position, shown by dotted lines in the same figure, the shaft sleeve 1 and thus also the propeller shaft is turned half a revolution, so that the boat will be driven backward. When the tiller is thereafter lowered to the firstmentioned position, the propeller shaft is turned back into the position for forward motion. This turning back of the propeller shaft takes place in a direction opposite to that of the first mentioned turning, which circumstance is of great importance, when the motor is being cooled by means of water, fed to the same from a pump, which revolves with the propeller shaft and which pump is directly connected with the motor through a hose, as this hose in consequence thereof does not become wound around the shaft sleeve.

It is evident that the arrangement described may also be used for steering the boat by raising or lowering the tiller from its position for motion forward. In this case the toothed segment 9 ought to be somewhat extended (to the right in Fig. 1) so as to enable the propeller shaft to be turned in both directions from the position just mentioned.

. The invention may be carried. out othersist of a straight rack connectedwith the tiller in a suitable manner and of acylindrical toothed wheel), though the arrange ment described is probably the simplest one.

Having now described my invent1on,what I claim as new and desire to secure by Let- I. Boat driving apparatus, comprising a propeller shaft having a propeller thereon,

means for supporting said shaft so that it can be swung in a horizontal plane, a steering tiller movable in a vertical plane, and connecting means between said tiller and propeller shaft, whereby the latter is swung when the former is moved in a vertical plane.

2. Boat driving apparatus, comprising a propeller shaft having a propeller thereon, means for supporting said shaft so that it can be swung in a horizontal plane, a steertiller movable in a vertical toothed segment connected to said tiller, a toothed wheel meshing with said segment, and a connection between the propeller shaft and the toothed wheel, whereby the former v is swung when the latter is rotated by the vertical movement of the tiller.

3. Boat driving apparatus, comprising a plane, a.

propeller shaft having a pro eller thereon, a casin in which said sha ismounted, means or supporting said casing so that it can be moved to swing the propeller shaft in a horizontal plane, a steering tiller movable in a vertical plane, a toothed segment connected to said tiller, a toothed wheel meshing with said segment, and a sleeve connecting said wheel with said casing, so

that the latter is swung when the former is rotated by the vertical movement tiller.

In witness whereof I have 'hereuntoset my hand in presence of two witnesses.
